Description

TECHNICAL FIELD

The present invention relates generally to a navigation system, and more particularly to a system for guidance delivery mechanism.

BACKGROUND ART

Modern portable consumer and industrial electronics, especially client devices such as navigation systems, cellular phones, portable digital assistants, and combination devices, are providing increasing levels of functionality to support modern life including location-based information services. Research and development in the existing technologies can take a myriad of different directions.
As users become more empowered with the growth of mobile location based service devices, new and old paradigms begin to take advantage of this new device space. There are many technological solutions to take advantage of this new device location opportunity. One existing approach is to use location information to provide navigation services such as a global positioning system (GPS) for a car or on a mobile device such as a cell phone, portable navigation device (PND) or a personal digital assistant (PDA).
Location based services allow users to create, transfer, store, and/or consume information in order for users to create, transfer, store, and consume in the “real world.” One such use of location based services is to efficiently transfer or route users to the desired destination or service.
Navigation systems and location based services enabled systems have been incorporated in automobiles, notebooks, handheld devices, and other portable products. Today, these systems aid users by incorporating available, real-time relevant information, such as maps, directions, local businesses, or other points of interest (POI). The real-time information provides invaluable relevant information.
However, a navigation system without guidance delivery mechanism has become a paramount concern for the consumer. The inability decreases the benefit of using the tool.
Thus, a need still remains for a navigation system with guidance delivery mechanism. In view of the increasing mobility of the workforce and social interaction, it is increasingly critical that answers be found to these problems. In view of the ever-increasing commercial competitive pressures, along with growing consumer expectations and the diminishing opportunities for meaningful product differentiation in the marketplace, it is critical that answers be found for these problems. Additionally, the need to reduce costs, improve efficiencies and performance, and meet competitive pressures adds an even greater urgency to the critical necessity for finding answers to these problems. Solutions to these problems have been long sought but prior developments have not taught or suggested any solutions and, thus, solutions to these problems have long eluded those skilled in the art.

Referring now to FIG. 1, therein is shown a navigation system 100 with guidance delivery mechanism in an embodiment of the present invention. The navigation system 100 includes a first device 102, such as a client or a server, connected to a second device 106, such as a client or server, with a communication path 104, such as a wireless or wired network.
For example, the first device 102 can be of any of a variety of mobile devices, such as a cellular phone, personal digital assistant, a notebook computer, automotive telematic navigation system, or other multi-functional mobile communication or entertainment device. The first device 102 can be a standalone device, or can be incorporated with a vehicle, for example a car, truck, bus, or train. The first device 102 can couple to the communication path 104 to communicate with the second device 106.
For illustrative purposes, the navigation system 100 is described with the first device 102 as a mobile computing device, although it is understood that the first device 102 can be different types of computing devices. For example, the first device 102 can also be a non-mobile computing device, such as a server, a server farm, or a desktop computer.
The second device 106 can be any of a variety of centralized or decentralized computing devices. For example, the second device 106 can be a computer, grid computing resources, a virtualized computer resource, cloud computing resource, routers, switches, peer-to-peer distributed computing devices, or a combination thereof.
The second device 106 can be centralized in a single computer room, distributed across different rooms, distributed across different geographical locations, embedded within a telecommunications network. The second device 106 can have a means for coupling with the communication path 104 to communicate with the first device 102. The second device 106 can also be a client type device as described for the first device 102.
In another example, the first device 102 can be a particularized machine, such as a mainframe, a server, a cluster server, rack mounted server, or a blade server, or as more specific examples, an IBM System z10™ Business Class mainframe or a HP ProLiant ML™ server. Yet another example, the second device 106 can be a particularized machine, such as a portable computing device, a thin client, a notebook, a netbook, a smartphone, personal digital assistant, or a cellular phone, and as specific examples, an Apple iPhone™, Palm Centro™, or Moto Q Global™.
For illustrative purposes, the navigation system 100 is described with the second device 106 as a non-mobile computing device, although it is understood that the second device 106 can be different types of computing devices. For example, the second device 106 can also be a mobile computing device, such as notebook computer, another client device, or a different type of client device. The second device 106 can be a standalone device, or can be incorporated with a vehicle, for example a car, truck, bus, or train.
Also for illustrative purposes, the navigation system 100 is shown with the second device 106 and the first device 102 as end points of the communication path 104, although it is understood that the navigation system 100 can have a different partition between the first device 102, the second device 106, and the communication path 104. For example, the first device 102, the second device 106, or a combination thereof can also function as part of the communication path 104.
The communication path 104 can be a variety of networks. For example, the communication path 104 can include wireless communication, wired communication, optical, ultrasonic, or the combination thereof. Satellite communication, cellular communication, Bluetooth, Infrared Data Association standard (IrDA), wireless fidelity (WiFi), and worldwide interoperability for microwave access (WiMAX) are examples of wireless communication that can be included in the communication path 104. Ethernet, digital subscriber line (DSL), fiber to the home (FTTH), and plain old telephone service (POTS) are examples of wired communication that can be included in the communication path 104.
Further, the communication path 104 can traverse a number of network topologies and distances. For example, the communication path 104 can include direct connection, personal area network (PAN), local area network (LAN), metropolitan area network (MAN), wide area network (WAN) or any combination thereof.
Referring now to FIG. 2, therein is shown an example of the first device 102 interacting with the second device 106 for sending a navigation request 204 to the second device 106. For clarity and brevity, the discussion of the present invention will focus on the first device 102 displaying the result generated by the navigation system 100. However, the second device 106 and the first device 102 can be discussed interchangeably.
The first device 102 can send the navigation request 204 to the second device 106. The navigation request 204 is defined as an entry by the user of the first device 102, the navigation system 100, or a combination thereof to request the second device 106 to generate navigation information 206 for reaching a destination 208. For example, the navigation request 204 can be “to downtown San Francisco, Calif. (CA)” from a current location 210.
The navigation information 206 is defined as a navigation guidance generated by the navigation system 100 to aid the user of the first device 102 to reach the destination 208. For example, the navigation information 206 can include a travel route 212, map information, an audio guidance, or a combination thereof. The destination 208 is defined as the target geographic location at the end of the travel route 212. The current location 210 is defined as the current geographic location of the first device 102. The travel route 212 is defined as the pathway generated by the navigation system 100 to guide the user of the first device 102 to reach the destination 208.
The navigation information 206 can include an information size 214, which is defined as an amount of data of the navigation information 206. For example, the information size 214 can be represented by the number of bytes. For another example, the information size 214 can represent an indexed range between a zero-based indexing to n-based indexing of an array data structure. More specifically, an array data structure can represent a collection of data objects. The array data structure can be indexed to indicate the position where the data object is stored in the array. The first position of the array can represent the zero base index. And the array can be indexed up to n-base indexing based on n-th position of the array.
The navigation information 206 can include an information segment 216, which is defined as a portion of the navigation information 206 segmented by the navigation system 100. For example, the information segment 216 can include a route portion, a portion representing a category of interest 218, a map information portion, an audio portion, a traffic information portion, or a combination thereof. For further example, the information segment 216 can represent a chunk of data for chunked transfer encoding of the Hypertext Transfer Protocol (HTTP). The category of interest 218 is defined as a broad breadth of interests by the user of the first device 102, such as coffee, restaurant, refueling station, or gym.
A representation example of the navigation information 206 after being chunked to generate the information segment 216 can be illustrated with the dotted lines connecting from the navigation information 206 to the information segment 216. For example, the navigation information 206 can include the map information. The map information portion of the navigation information 206 can be chunked to generate the information segment 216 representing the map information.
The information segment 216 can include a segment size 220, which is defined as an amount of data for the information segment 216. For example, the segment size 220 can be represented by the number of bytes. For another example, the segment size 220 can represent an indexed range between a zero-based indexing to n-based indexing of the array data structure.
The segment size 220 can be changed based on a network quality 222, a carrier type 224, a platform type 226, the information size 214, or a combination thereof. Details regarding the network quality 222, the carrier type 224, the platform type 226, the information size 214, or a combination thereof influencing the segment size 220 will be discussed later.
The information segment 216 can include a subsegment 228, which is defined as a portion of the information segment 216 segmented by the navigation system 100. For example, the information segment 216 can represent the map information portion of the navigation information 206. The map information portion can include a plurality of the subsegment 228 representing a sign portion, a road portion, or a combination thereof. The sign portion can include the navigation information 206 related to street names. The road portion can include the navigation information 206 related to freeways and local loads for a geographic area of the current location 210. A size of the subsegment 228 can change based on the similar factor as discussed for the segment size 220 above.
The information segment 216 can include an information type 230, which is defined as a category of the navigation information 206. For example, the information type 230 can include route information, map information, audio information, the category of interest information, or a combination thereof. More specifically, the information segment 216 having the data for the travel route 212 can represent the information type 230 of the route information.
A display interface 202 of the first device 102 can display the information segment 216 each individual type of the information type 230 separately. For example, the display interface 202 can display the information segment 216 with the information type 230 of the route information. More specifically, the display interface 202 can display the travel route 212 without the map information or the audio information.
A plurality of the information segment 216 can be combined to form a segment combination 232. For example, the segment combination 232 can include a combination of the information type 230 of the route information and the audio information. More specifically, the audio information can overlay the route information as the segment combination 232. The navigation system 100 can transmit the segment combination 232 to the first device 102 rather than sending each of the information segment 216 to the first device 102. As a result, the first device 102 can display the route information on the display interface 202 with the audio information providing audio guidance to the user simultaneously.
The navigation system 100 can generate a transmission sequence 234, which is defined as an arrangement of the information segment 216. Based on the transmission sequence 234, the navigation system 100 can send the navigation information 206 to the first device 102.
For example, the transmission sequence 234 can include a plurality of the information segment 216 with a plurality of the information type 230. For further example, the navigation system 100 can transmit the navigation information 206 to the first device 102 based on the transmission sequence 234 by transmitting the information segment 216 in a following order: 1. Route information; 2 Traffic information; 3. Map information; 4. Audio information; and 5. Category of interest information. The transmission sequence 234 can be rearranged based on a user's preference 236, a travel condition 238, or a combination thereof. Details regarding a rearrangement of the transmission sequence 234 will be discussed later.
For example, the user's preference 236 can be prioritizing a transmission of the information segment 216 with the information type 230 of the traffic information to the first device 102 during the hours of morning commute. For another example, the user's preference 236 can be prioritizing the transmission of the information segment 216 with the information type 230 of the category of interest information to the first device 102 during the weekend.
The travel condition 238 is defined as a circumstance that can exist at the time when the user of first device 102 is traveling, plan to travel, or a combination thereof. For example, the travel condition 238 can be rainy weather when the user of the first device 102 is commuting to work. For another example, the navigation system 100 can factor in the Independence Day festivity as the travel condition 238 for traveling during over the weekend.
The network quality 222 is defined as a quality of the communication path 104. For example, the network quality 222 can include strength or coverage of telecommunication service available within a geographic region. For another example, to determine the network quality 222, the navigation system 100 can consider an availability of a network type, a transmission mode, a transmission speed 240, or a combination thereof. For different example, the network quality 222 can include a bandwidth of the communication path 104.
The carrier type 224 is defined as a type of a telecommunication service operating with the first device 102 over the communication path 104. For example, the carrier type 224 can include AT&T™, Verizon™, or Sprint™, which they are telecommunication companies that provide mobile telecommunication services in the United States. For further example, the carrier type 224 can be represented as Carrier A or Carrier B.
The platform type 226 is defined as a type of the first device 102. For example, the platform type 226 of the first device 102 used by the user can be an iPhone™ with iOS™ operating system. For different example, the platform type 226 can be Samsung Galaxy™ with Android™ operating system. For further example, the platform type 226 of the first device 102 can be represented as Platform A or Platform B.
The navigation system 100 can consider the transmission speed 240 to determine the network quality 222. For example, the transmission speed 240 can include a rate of data transfer between the second device 106 and the first device 102. For specific example, the transmission speed 240 for transmitting the information segment 216 representing the route information can be 1 megabit per second (Mbps). Further, the navigation system 100 can consider the transmission speed 240 permitted by the carrier type 224, the platform type 226, or a combination thereof. Details regarding the consideration will be discussed later.
The navigation system 100 can consider a quality threshold 242 to determine the network quality 222. For example, the quality threshold 242 can represent the minimum level of decibel for signal-to-noise ratio (SNR), delay time, the transmission speed 240, amplitude, signal power unit in watts, or a combination thereof for transmitting a signal. For specific example, the navigation system 100 can segment the navigation information 206 to generate the information segment 216 if the decibel level of the wireless signal from the cell tower dips below the quality threshold 242. For another example, the navigation system 100 can segment the navigation information 206 to generate the information segment 216 if the delay time of receiving the wireless signal exceeds the quality threshold 242.
Referring now to FIG. 3, therein is shown an example of a variation 302 of the transmission sequence 234. The variation 302 is defined as a rearrangement of the transmission sequence 234 based on various factors. For example, the variation 302 of the transmission sequence 234 can include the order of transmitting the route information first, followed by the transmission of the category of interest information, the map information, and the audio information to the first device 102 of FIG. 1.
For different example, the variation 302 of the transmission sequence 234 can include only transmitting the information type 230 of the route information and the traffic information. For another example, the variation 302 of the transmission sequence 234 can include a combination of the information segment 216 and the subsegment 228, the subsegment 228 sent individually along with the information segment 216 to the first device 102.
For different example, the variation 302 of the transmission sequence 234 can include the segment combination 232 including the route information and traffic information being transmitted before the information type 230 of the audio information. Details regarding the navigation system 100 generating the variation 302 of the transmission sequence 234 will be discussed later.
Referring now to FIG. 4, therein is shown an example of the network quality 222, the carrier type 224, the platform type 226 of FIG. 2, or a combination thereof impacting a generation of the transmission sequence 234 for transmitting the information segment 216. For example, the variation 302 of the transmission sequence 234 can be generated based on the network quality 222, the carrier type 224, the platform type 226, or a combination thereof.
For specific example, the carrier type 224 can be Carrier A. Carrier A can offer the network quality 222 that is better than another of the carrier type 224 of Carrier B. More specifically, the transmission speed 240 of FIG. 2 can be better with Carrier A than Carrier B. The user of the first device 102 can subscribe to Carrier A for mobile phone service. The navigation system 100 can transmit the information segment 216 with the transmission sequence 234 that includes the route information and the category of interest information to the first device 102. In contrast, if the user of the first device 102 subscribes to Carrier B, the navigation system 100 can transmit with the transmission sequence 234 that includes the information segment 216 and the subsegment 228 to reduce the burden for transmitting a large size data over the communication path 104.
For further example, the variation 302 of FIG. 3 of the transmission sequence 234 can be based on the information size 214 of FIG. 2 of the navigation information 206 of FIG. 2, the segment size 220 of the information segment 216, or a combination thereof. As discussed previously, Carrier A can offer the network quality 222 that is better than Carrier B. The data size of the segment combination 232 that includes the route information and the category of interest information can be larger than the information segment 216 representing the route information.
Continuing with the example, the navigation system 100 can transmit the segment combination 232 with the route information and the category of interest information over the communication path 104 offered by Carrier A because of the network quality 222 offered by Carrier A. In contrast, the navigation system 100 can transmit with the transmission sequence 234 that includes the information segment 216 of the route information and the subsegment 228 of sign information only. The navigation system 100 can determine not to send the segment combination 232 with the route information and the category of interest information over the communication path 104 offered by Carrier B to minimize the burden on the communication path 104.
For another example, the navigation system 100 can change the transmission sequence 234 based on the network quality 222. More specifically, the navigation system 100 can change the segment size 220 based on whether the strength of the wireless is meeting or exceeding the quality threshold 242 of FIG. 2. For different example, the navigation system 100 can change the variation 302 of the transmission sequence 234 based on the capability of the platform type 226 for accepting the information segment 216. More specifically, if an interference level that causes a delay for receiving the wireless signal exceeds the quality threshold 242, the navigation system 100 can send only the subsegment 228 to reduce the delay time. Details will be discussed later.
Referring now to FIG. 5, therein is shown a first example of a sequence diagram. More specifically, the sequence diagram can illustrate the interaction between the first device 102 and the second device 106.
For example, the first device 102 can transmit the navigation request 204. The navigation request 204 can be partitioned by the second device 106 to interact with variety of services available in the second device 106. For example, the second device 106 can include the route service to generate the information segment 216 representing the route information.
For further example, the second device 106 can interact with the variety of services in accordance to the transmission sequence 234 of FIG. 2. More specifically, the transmission sequence 234 can represent: 1. Route information; 2 Map information; 3. Audio information; and 4. Shortest Path Tree (SPT) information. Based on the transmission sequence 234, the second device 106 can interact with the route service first to generate the information segment 216 representing the route information. Next, the second device 106 can interact with the map service to generate the information segment 216 representing the map information. SPT can represent a path, generated based on Dijkstra Algorithm, that has a shortest physical distance between one node to another node. The node can represent a decision point where the navigation system 100 can decide how to proceed with the travel.
In response to the navigation request 204, the second device 106 can transmit the plurality of the information segment 216 in the order based on the transmission sequence 234. More specifically, the first device 102 can receive the plurality of the information segment 216 based on the transmission sequence 234 of: 1. Route information; 2 Map information; 3. Audio information; and 4. SPT information.
Referring now to FIG. 6, therein is shown a second example of the sequence diagram. More specifically, the sequence diagram can illustrate the interaction between the first device 102 and the second device 106 for transmitting the subsegment 228. As discussed in FIG. 5, after the second device 106 received the navigation request 204, the second device 106 can generate the subsegment 228 to be displayed on the first device 102. More specifically, the subsegment 228 can be transmitted to the first device 102 based on the transmission sequence 234.
For further example, the subsegment 228 can be generated from the information segment 216 of FIG. 2 representing the map information. “MAP 1” can represent the subsegment 228 representing the sign portion of the map information. “MAP 2” can represent the subsegment 228 representing the road portion. “MAP N” can represent the n-th number of the subsegment 228. The n-th number of the subsegment 228 can be generated based on the partitioning of the information segment 216.
Referring now to FIG. 7, therein is shown an exemplary block diagram of the navigation system 100. The navigation system 100 can include the first device 102, the communication path 104, and the second device 106. The first device 102 can send information in a first device transmission 708 over the communication path 104 to the second device 106. The second device 106 can send information in a second device transmission 710 over the communication path 104 to the first device 102.
For illustrative purposes, the navigation system 100 is shown with the first device 102 as a client device, although it is understood that the navigation system 100 can have the first device 102 as a different type of device. For example, the first device 102 can be a server.
Also for illustrative purposes, the navigation system 100 is shown with the second device 106 as a server, although it is understood that the navigation system 100 can have the second device 106 as a different type of device. For example, the second device 106 can be a client device.
For brevity of description in this embodiment of the present invention, the first device 102 will be described as a client device and the second device 106 will be described as a server device. The present invention is not limited to this selection for the type of devices. The selection is an example of the present invention.
The first device 102 can include a first control unit 712, a first storage unit 714, a first communication unit 716, a first user interface 718, and a location unit 720. The first control unit 712 can include a first control interface 722. The first control unit 712 can execute a first software 726 to provide the intelligence of the navigation system 100. The first control unit 712 can be implemented in a number of different manners. For example, the first control unit 712 can be a processor, an embedded processor, a microprocessor, a hardware control logic, a hardware finite state machine (FSM), a digital signal processor (DSP), or a combination thereof. The first control interface 722 can be used for communication between the first control unit 712 and other functional units in the first device 102. The first control interface 722 can also be used for communication that is external to the first device 102.
The first control interface 722 can receive information from the other functional units or from external sources, or can transmit information to the other functional units or to external destinations. The external sources and the external destinations refer to sources and destinations physically separate to the first device 102.

The segment generator module 820 includes a customization module 822. The customization module 822 customizes the segment size 220 of the information segment 216. For example, the customization module 822 can customize the segment size 220 based on the network quality 222 for improving the transmission speed 240 of the information segment 216 to the first device 102.
The customization module 822 can increase or decrease the segment size 220 for customizing the segment size 220. More specifically, the information type 230 of the information segment 216 can represent the map information. For example, the map information can have the segment size 220 of 10 megabytes. The customization module 822 can decrease the segment size 220 of the information segment 216 by splitting the map information to two portions of 7 megabytes each.
For specific example, the customization module 822 can increase or decrease the segment size 220 based on the network quality 222 meeting, exceeding, or dipping below the quality threshold 242. More specifically, if a wireless signal power is less than the quality threshold 242, the customization module 822 can generate the information segment 216 by segmenting the navigation information 206 with smaller of the segment size 220 than if the wireless single power had met or was greater than the quality threshold 242.
It has been discovered that the navigation system 100 reduces a transaction time for displaying the information segment 216 on the display interface 202 by factoring the network quality 222. The segment size 220 can be reduced if the network quality 222 dips below the quality threshold 242. Subsequently, the burden on the communication path 104 for transmitting the information segment 216 can be reduced. As a result, the first device 102 can display the information segment 216 more quickly and efficiently for safer operation of the navigation system 100 or the vehicle.
For different example, the customization module 822 can customize the segment size 220 based on the carrier type 224 for improving the transmission speed 240 of the information segment 216 to the first device 102. For specific example, if the carrier offers the 4G LTE network, the customization module 822 can increase the segment size 220 for the carrier type 224. For different example, if the user of the first device 102 travels abroad, and the carrier at the traveled location offers the 3G network, the customization module 822 can decrease the segment size 220 for the carrier type 224.
It has been discovered that the present invention can reduce the transaction time for displaying the information segment 216 on the display interface 202 by factoring the carrier type 224. The segment size 220 can be reduced if the carrier type 224 changes as the wireless service offered by the carrier is changed from 4G LTE network to 3G network. Subsequently, the burden on the communication path 104 for transmitting the information segment 216 can be reduced. As a result, the first device 102 can display the information segment 216 more quickly and efficiently for safer operation of the navigation system 100 or the vehicle.
For another example the customization module 822 can customize the segment size 220 based on the platform type 226 for improving the transmission speed 240 of the information segment 216 to the first device 102. For specific example, the customization module 822 can generate the information segment 216 with the segment size 220 suitable for the capacity offered by the first storage interface 724. If the user of the first device 102 changes the first device 102 from Platform A to Platform B, and the Platform B having more capacity, the customization module 822 can increase the segment size 220 to take advantage of the greater capacity of the first storage interface 724 for Platform B.
It has been discovered that the present invention can reduce the transaction time for displaying the information segment 216 on the display interface 202 by factoring the platform type 226. The segment size 220 can be reduced if the first storage interface 724 becomes smaller as the user of the first device 102 changed the platform type 226 of the first device 102. Subsequently, the burden on the first device 102 for processing the information segment 216 can be reduced. As a result, the first device 102 can display the information segment 216 more quickly and efficiently for safer operation of the navigation system 100 or the vehicle.
For different example, the customization module 822 can customize the segment size 220 based on the travel condition 238 for improving the transmission speed 240 of the information segment 216 to the first device 102. For specific example, the customization module 822 can generate the information segment 216 with the segment size 220 that is larger in the rural geographic area than the urban geographic area. For example, the rural geographic area can be a geographic area where the population is sparse. More specifically, the rural geographic area may not require quicker update of the navigation information 206. Moreover, the navigation information 206 may contain less data for the rural geographic area. As a result, the segment generator module 820 may not require to segment the navigation information 206 frequently. The customization module 822 can generate the information segment 216 with the greater of the segment size 220 as the demand to update the navigation information 206 is less frequent in the rural geographic area.
It has been discovered that the present invention can reduce the transaction time for displaying the information segment 216 on the display interface 202 by factoring the travel condition 238. The segment size 220 can be reduced if the displaying of the information segment 216 warrants a quicker display due to the travel condition 238. For example, in an urban geographic area, the user of the first device 102 can desire the update on the display 202 for the information segment 216 more quickly and efficiently than if the user was traveling in the rural geographic area. By generating the information segment 216 with the segment size 220 that is reduced, the first device 102 can update the display more quickly and efficiently. As a result, the first device 102 can display the information segment 216 more quickly and efficiently for safer operation of the navigation system 100 or the vehicle.
For another example, the customization module 822 can customize the segment size 220 based on the information size 214 for improving the transmission speed 240 of the information segment 216 to the first device 102. For specific example, if the information size 214 of the navigation information 206 is greater than the capacity that the first storage interface 724 can handle, the customization module 822 can generate the information segment 216 with the segment size 220 based on a capacity size that the first storage interface 724 can handle.
The segment generator module 820 includes a subsegmentation module 824. The subsegmentation module 824 can generate the subsegment 228 of FIG. 2 similarly as the customization module 822. More specifically, the data size of the subsegment 228 after segmenting the information segment 216 can base on the similar factors as determining the segment size 220 of the information segment 216. For example, the subsegmentation module 824 can generate the subsegment 228 for further segmenting the information segment 216 for improving the transmission speed 240 of the information segment 216 to the first device 102.
It has been discovered that the present invention can reduce the transaction time for displaying the information segment 216 on the display interface 202 by generating the subsegment 228. The burden on the communication path 104 for transmitting the information segment 216 can be reduced by sending the smaller size of the subsegment 228. As a result, the first device 102 can display the information segment 216 more quickly and efficiently for safer operation of the navigation system 100 or the vehicle.
For illustrative purposes, the navigation system 100 is shown with the customization module 822 increasing or decreasing the segment size 220 of the information segment 216, although it is understood that the customization module 822 can be operated differently. For example, the customization module 822 can increase or decrease the segment size 200 based on including or excluding the subsegment 228.
For specific example, the information type 230 of the information segment 216 can represent the map information. The map information can include the plurality of the subsegment 228 representing the sign portion and the road portion. The customization module 822 can increase the segment size 220 by having both of the sign portion and the road portion as part of the information segment 216. In contrast, the customization module 822 can decrease the segment size 220 by only including the sign portion for the information segment 216.
The navigation system 100 can include a prioritizer module 826, which can be coupled to the segment generator module 820. The prioritizer module 826 prioritizes which of the information type 230 of the information segment 216 should be transmitted as a priority to the first device 102. For example, the prioritizer module 826 can prioritize the information type 230 for transmitting the information segment 216 to the first device 102.
The prioritizer module 826 can prioritize in a number of ways. For example, the prioritizer module 826 can prioritize the information type 230 based on the user's preference 236. For specific example, the user's preference 236 can indicate that the user of the first device 102 can desire that he or she would like to have the information type 230 representing the traffic information during the morning commute. The prioritizer module 826 can prioritize the transmission of the information segment 216 representing the traffic information first based on the user's preference 236.
For different example, the prioritizer module 826 can prioritize the information type 230 based on the network quality 222. More specifically, if the network quality 222 fails to meet the quality threshold 242, the prioritizer module 826 can prioritize the transmission of the information segment 216 with the smaller of the segment size 220 over other of the information segment 216 with the larger of the segment size 220. For specific example, the plurality of the information type 230 for the information segment 216 can include the route information and the map information. The map information can be have larger of the segment size 220 than that of the route information. The network quality 222 can be below the quality threshold 242. The prioritizer module 826 can prioritize the information type 230 for the route information to be transmitted prior to transmitting the information segment 216 based on the network quality 222.
For another example, the prioritizer module 826 can prioritize the information type 230 based on the carrier type 224. If Carrier A offers the 4G LTE network for the communication path 104, the prioritizer module 826 can prioritize the transmission of the information type 230 with a large data size. More specifically, the information type 230 for the map information can represent the large data size, as the information segment 216 can include the plurality of the subsegment 228, such as the road name information and the sign information. If the communication path 104 is 4G LTE network compliant, because of the larger bandwidth than the 3G network, the prioritizer module 826 can prioritize the transmission of the information type 230 having the segment size 220 that is large.
For different example, the prioritizer module 826 can prioritize the information type 230 based on the platform type 226. For specific example, the first device 102 can represent Platform A. For further example, the first control unit 712 of FIG. 7 can process the graphics information of the map information better than Platform B. As a result, the prioritizer module 826 can give a higher priority for the second device 106 to transmit the information type 230 of map information based on the platform type 226. More specifically, the prioritizer module 826 can allow the map information to be transmitted first to the first device 102 with the platform type 226 of Platform A than if the platform type 226 of Platform B.
It has been discovered that the present invention can reduce the transaction time for displaying the information segment 216 on the display interface 202 by prioritizing the information type 230. The prioritization of the information type 230 improve the transaction time for displaying the information segment 216 on the first device 102 by transmitting the information type 230 with the smaller of the information segment 216 more quickly and efficiently prior to transmitting the information segment 216 with the larger of the segment size 220. As a result, the first device 102 can display the information segment 216 efficiently for safer operation of the navigation system 100 or the vehicle.
The navigation system 100 can include a combination module 828, which can be coupled to the prioritizer module 826. The combination module 828 combines the plurality of the information segment 216. More specifically, the combination module 828 can combine a plurality of the information type 230 to generate the segment combination 232 of FIG. 2. For example, the combination module 828 can generate the segment combination 232 based on combining the plurality of the information segment 216 for customizing the navigation information 206 displayed on the first device 102.
The combination module 828 can generate the segment combination 232 in a number of ways. For example, the combination module 828 can generate the segment combination 232 based on the user's preference 236. The user's preference 236 can desire to always have the plurality of the information type 230 representing the route information and the audio information. The combination module 828 can generate the segment combination 232 having the plurality of the information segment 216 representing the route information and the audio information.
It has been discovered that the present invention can enhance the safe operation of the navigation system 100 by generating the combination of the information segment 216 desired by the user's preference 236. The segment combination 232 can include the information type 230 most pertinent to the user of the first device 102. As a result, the first device 102 can display the information segment 216 most relevant to the user for safer operation of the navigation system 100 or the vehicle.
For different example, the combination module 828 can generate the segment combination 232 based on the network quality 222. For specific example, the generation of the segment combination 232 can differ based on how much below the network quality 222 compared is to the quality threshold 242. If the strength of the wireless signal is only 1% decibel below the quality threshold 242, the combination module 828 can generate the segment combination 232 having five of the information segment 216. In contrast, if the strength of the wireless signal is 20% decibel below the quality threshold 242, the combination module 828 can generate the segment combination 232 having two of the information segment 216. More specifically, the two of the information segment 216 can represent the information segment 216 having smallest of the data size out of the five of the information segment 216.
It has been discovered that the present invention can reduce a transaction time for displaying the segment combination 232 on the display interface 202 by factoring the network quality 222. The combination of the segment combination 232 can be altered if the network quality 222 dips below the quality threshold 242. Subsequently, the burden on the communication path 104 for transmitting the segment combination 232 can be reduced. As a result, the first device 102 can display the segment combination 232 more quickly and efficiently for safer operation of the navigation system 100 or the vehicle.
The navigation system 100 can include a sequence generator module 830. The sequence generator module 830 generates the transmission sequence 234 of FIG. 2. For example, the sequence generator module 830 can generate the transmission sequence 234 for prioritizing the information type 230 of the information segment 216 for displaying the information segment 216 on the first device 102.
The sequence generator module 830 can generate the transmission sequence 234 in a number of ways. For example, the sequence generator module 830 can generate the transmission sequence 234 based on the prioritization of the information type 230 generated by the prioritizer module 826. For specific example, if the prioritizer module 826 designated the information type 230 of the route information as the highest priority, the sequence generator module 830 can generate the transmission sequence 234 with the route information as first of the information segment 216 to be transmitted.
For different example, the sequence generator module 830 includes a variety module 832. The variety module 832 can generate the variation 302 of FIG. 3 of the transmission sequence 234. For example, the variety module 832 can dynamically generate the variation 302 of the transmission sequence 234 based on various factors.
For specific example, the variety module 832 can generate the variation 302 based on the network quality 222. As the user of the first device 102 travels along the travel route 212, the distance between the first device 102 and the cell tower can change. The network quality 222 can change as the wireless signal strength can change based on the current location 210 relative to the cell tower. Based on the changes of the network quality 222, the variety module 832 can generate the variation 302 to rearrange the transmission sequence 234.
More specifically, the map information can represent the largest of the data size compared to the route information or the audio information. If the wireless signal strength is 1% below the quality threshold 242, the sequence generator module 830 can generate the transmission sequence 234 with the information type 230 in the order of the map information, the route information, and the audio information. The map information can still be sent first, as the wireless signal strength only dropped 1% below the quality threshold 242.
In contrast, if the wireless signal strength drops 10% below the quality threshold 242, the variety module 832 can rearrange the transmission sequence 234 in the order of the route information, the audio information, and the map information. The rearrangement of the transmission sequence 234 allows the transmission of the information segment 216 having the smaller of the segment size 220 before the bigger of the segment size 220 to avoid network latency due to clogging of the communication path 104 with the bigger data size.
It has been discovered that the present invention can reduce a transaction time for displaying the information segment 216 on the display interface 202 based on rearranging the transmission sequence 234 by factoring the network quality 222. The transmission sequence 234 can be rearranged if the network quality 222 dips below the quality threshold 242. Subsequently, the burden on the communication path 104 for transmitting the information segment 216 can be reduced. As a result, the first device 102 can display the information segment 216 more quickly and efficiently for safer operation of the navigation system 100 or the vehicle.
For different example, the variety module 832 can generate the variation 302 based on the travel condition 238. For example, the variety module 832 can update the transmission sequence 234 based on the travel condition 238 for rearranging the information segment 216 for transmitting the information segment 216 to the first device 102.
If the travel condition 238 for traversing along the travel route 212 is sunny and dry, the sequence generator module 830 can generate the transmission sequence 234 in the order of the route information, the map information, and the road condition information. In contrast, if the travel condition 238 changes to rainy and wet condition, the variety module 832 can rearrange the transmission sequence 234 in the order of the route information, the road condition information, and the map information. The information segment 216 representing the road condition information can be transmitted before the information segment 216 representing the map information, as the user of the first device 102 can desire the road condition information more when the road condition for the travel route 212 deteriorates.
It has been discovered that the present invention can display the information segment 216 on the display interface 202 most pertinent to the user of the first device 102 based on rearranging the transmission sequence 234 by factoring the travel condition 238. The transmission sequence 234 can be rearranged as the travel condition 238 changes from traversing the travel route 212. As a result, the first device 102 can display the information segment 216 based on the travel condition 238 more quickly and efficiently for safer operation of the navigation system 100 or the vehicle.
For another example, the variety module 832 can generate the variation 302 based on the user's preference 236. For example, the variety module 832 can update the transmission sequence 234 based on the user's preference 236 for rearranging the information segment 216 for transmitting the information segment 216 to the first device 102. More specifically, even if the wireless signal strength dips below the quality threshold 242, the user of first device 102 can desire the segment combination 232 of the plurality of the information segment 216 representing the route information and the audio information to be always be simultaneously transmitted first to the first device 102. The variety module 832 can generate the variation 302 based on the user's preference 236 to include the segment combination 232 of the route information and the audio information.
It has been discovered that the present invention can display the information segment 216 on the display interface 202 most pertinent to the user of the first device 102 based on rearranging the transmission sequence 234 by factoring the user's preference 236. The transmission sequence 234 can be rearranged to transmit the information segment 216 most desired by the user. As a result, the first device 102 can display the information segment 216 that is most pertinent to the user more quickly and efficiently for safer operation of the navigation system 100 or the vehicle.
The navigation system 100 can include a display module 834, which can be coupled to the sequence generator module 830. The display module 834 displays the information segment 216 on the first device 102. For example, the display module 834 can display the information segment 216 based on the transmission sequence 234 generated by the second device 106.
The display module 834 can display the information segment 216 in a number of ways. For example, the display module 834 can display the information segment 216 in the order specified on the transmission sequence 234. More specifically, the display module 834 can display the information segment 216 as the display module 834 receives the information segment 216. For different example, in contrast, the display module 834 can display the navigation information 206 after all of the information segment 216 have been transmitted to the first device 102.
It has been discovered that the present invention can display the information segment 216 on the display interface 202 more quickly by displaying the information segment 216 in the order the first device 102 received. The first device 102 can display the portion of the navigation information 206 as soon as it receives rather than waiting for the entire data set for the navigation information 206 to be downloaded. As a result, the first device 102 can display the information segment 216 more quickly and efficiently for safer operation of the navigation system 100 or the vehicle.
The physical transformation from traveling along the travel route 212 results in movement in the physical world, such as people using the first device 102, the vehicle, or a combination thereof, based on the operation of the navigation system 100. As the movement in the physical world occurs, the movement itself creates additional information that is converted back into the segment size 220, the transmission sequence 234, the variation 302, or a combination thereof for the continued operation of the navigation system 100 and to continue the movement in the physical world.
